顺序指示模拟方法是以指示克里金为基础的一种随机模拟方法。在濮城油田东区沙二下储层非均质性研究中，采用该方法对沙二下亚段的渗透率进行了研究，并与普通克里金法建立的模型进行了对比。结果表明，普通克里金法具有平滑效应，不宜用来研究储层的非均质性。而顺序指示模拟方法更能反映参数的细节变化，并能够表征由于缺乏资料等原因而引起的不确定性。因此，该方法更适合储层非均质性的研究。
The sequential indication simulation method is a stochastic simulation based on the indication of kriging. In the study of reservoir heterogeneity in the second sand area of Pucheng Oilfield, the permeability of the second sub-section of Shaheer is studied and compared with the model established by ordinary Kriging method. The results show that the ordinary Kriging method has a smooth effect and should not be used to study the reservoir heterogeneity. The sequential indicator simulation method can better reflect the details of the parameters and can characterize the uncertainty caused by lack of data and other reasons. Therefore, this method is more suitable for reservoir heterogeneity research.
